Laptop caps and number button blink at the same time once

[Masen2016]

I was performing updates on the computer when the battery power died and when provided the power cord I had a black screen and the caps and number button appears to blink once at the same time. I upgraded the operating system about 1 month ago to Windows 7 and it has been working fine until the updates began to update.

Hey there @Masen2016! Thanks for stopping by the HP Support Forums!

I understand that you are getting a black screen on your laptop.

As you mentioned that the light on caps and num lock are blinking once repeatedly.

This indicates it could be a problem with the processor.

Please contact HP phone support and check for service options.

However, you can try few steps mentioned below.

1. Turn off the computer.

2. Remove the computer from any port replicator or docking station.

3. Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.

4. Unplug the AC adapter from the computer.

5. Remove the battery from the battery compartment.

6. Press and hold down the Power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory.

7. Insert the battery and plug the AC adapter back into the notebook computer, but do not connect any of the peripheral devices.

8. Press the Power button to turn on the computer.

9. If you are comfortable in removing the memory and hard drive from your laptop. Please remove the parts clean it and put them back in.

 
Let me know how it goes.                     

Have a great day!

Thank you for your reply. I did as you suggested took that'd drive and ram out and cleaned but still had the black screen and blinking of caps and number button once. Can I change the processor to icore 3? What specs should I be concerned with before purchasing?

Hey there @Masen2016!

Thanks for the reply as lights on caps and num lock are blinking once everytime.

This indicates it could be a problem with the processor,

And you cannot upgrade a processor on a laptop as the as system configuration in written in BIOS.

If you upgrade any part laptop would malfunction.

So you can contact HP and get the unit serviced.
